SAFE, VAULT, 62.0.

Specification of Letters Patent.

Patented June 12, 1906.

To all whom ?lt may concern:

Be it known that I, THEODOR HENRY HOL- STEIN, a citizen of the United States, residing at Hamilton, in the county of Butler and and like structures having heavy doors; and

it oonsists in a novel construction' and arrangement whereby the door may be withdrawn from its seat or Opening and moved or swung out of the way, even though it be the inner door or closure of a deep-seated opening.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a horizontal sectional view of a safe having an inner and an outer door, the inner one mounted in accordance with my invention; Fig. 2, a face view of the inner door and its surroundings, the body of the safe being shown in section on line 2 2 of Fig. l and the door partially broken away. Fig. 3 is a view showing the door moved outward and also 'showing by dotted lines its final position in swinging aside to leave the Opening unobstructed, parts being shown' in section; and Figs. 4, 5, and 6, sectional detail Views of the antifriction bearings or supports upon which the door moves lengthwise of the hinge-bar, taken on line4 4 of Fig. 1 and lines 5 5 and 6 6 of Fig. 2, respectively.

The invention is here illustrated as embodied in a hollow-walled or fireproof safe having inner and outer doors, the inner one of circular form; but it is applicable to safes and vaults generally and to doors* of any shape. The fastening devices may be of any usual or desired type and are wholly omitted from the drawings, because constituting no part of the present invention.

Referri ng to the drawings, A indicates a safe shown with a double front, having an outer door B and an inner door C, the latter provided with the improved hinge or support.

It will be apparent upon referring to Fig. 1 that if door O were merely hung to the inner jamb or to the face of the inner safe-front it would when opened outward occupy a considerable amount of the space of the outer doorway and would to a considerable degree obstruct the inner doorway. To avoid this result, I provide a long and heavy bar D, connected by a substantial pin E to its complemental leaf or member F after the manner of a common T-hinge to support and carry the door. The leaf F is bolted or otherwise made fast to the front or j amb to which the door is to be hung, and the bar D swings about pin E, so that the door O may be swung to and fromits seat, as it would be upon any common hinge. It will be observed, however, upon referring to Figs. 1, 2, 3, and 4 that the bar Dis in two parts a and b, connected one to the other by a knuckle or hinge joint c. This joint is produced by forming the two members a and b with interlocking fingers or tenons, through which passes a pin d, the tenons being advisably somewhat longer than the thickness of the bar and beveled, as shown in Figs. 1 and 3, so that when the door is upon the outer section of the bar the bar may be buckled or broken at the knuckle, so that the outer section b shall stand at an angle to the inner section a, as best seen in Fig. 3. So long, however, as the door is upon the inner section a of the bar D thejoint or knuckle cannot be broken; but the two parts will be held in alinement by the door in contact with the rear or inner face of the bar.

To permit the door to move u on the bar D and lengthwise thereof, a box-li (e strap G is passed about three sides of the bar and bolted or otherwise made fast to the door, as seen in the several figures. The strap G fits quite closely to the front face and upper and lower edges of the bar D and is drawn by its fastening bolts or screws snugly against the safedoor, against which the bar D is also closely held, but not so closely as to preclude free movement of the door and strap G upon and relatively to the bar. To guard against binding or cramping and reduce friction to a minimum, antifriction-rollers c and f are arranged vertically in front and in rear of bar D, being seated in the strap and the door, respectively, as seen in Figs. 3 and 6, and other rollers g and h are arranged horizontally above and below said bar, their aXles or journals being seated in the strap and in door C, as shown in Fig. 5. Any convenient form of roller-bearing or rolling-support may be employed, the top rollers being obviously the most important, since the weight falls principally upon them. 7

IOO

l`he parts being thus constructed operateas follows: Assuming that the doorCis closed, as in Fig. 1, it will be opened by swinging the bar D about its hinge-pin E until the bar assumes approximately the position indicated in Fig. 3, whereupon the door C will be sld or rolled outward thereon to the position in which it is shown by full lines in said figure.

Having passed the joint c of bar D, the door ,or to place them therein.

lt is deemed desirable to provide the rollerbearings or antifriction-supports for the door upon the bar D but this is optional and not essential. Two or more such supports may of course be provided, and for very heavy doors this may be found advisable. Measurably good results may be attained without the joint c; but its use is highly advantageous. A stop is provided to prevent the door 'from leaving bar D.

Having thus described my invention, what I Claim is- 1. In combination with a vault, safe, or other structure having an inner and an outer wall separated one from the other and each provided with a doorway or Opening, a bar hinged at a point within the space between the two walls and adapted to swing inward across the inner doorway and outward through the outer doorway, and a door carried by said bar and movable longitudinally thereon, whereby it is adapted to be carried through the outer doorway and all'ord a clear way to the inner doorway.

2. In combination with a safe, vault or structure provided with an Opening or doorway, a two-part bar hinged to the structure and adapted to swing across the Opening; and. a door or closure carried by and arranged to move lengthwise oi' said. bar, the two sections of the bar being hinged or jointed one to the other, substantially as shown and described.

3. In combination with a safe, vault, or other structure having an inner and an outer wall separated one from the other and each prov-ided with a doorway or Opening, a door or closure C adapted to close the inner doorway, and a support for said. door, comprising a bar hinged to the structure between the two walls and adapted to swing through the outer doorway, and a strap or slide G secured to the door and passing about said bar, substantially as described, whereby the door C may be moved through the outer doorway to afford a clear passage to the inner doorway.

4. In combination With a safe, vault or other structure having a doorway or Opening, a door or closure therefor, a support for said door comprising a bar hinged to the structure, a strap or slide secured to the door and passing about the bar, and antifriction-rollers interposed between the bar and the strap or slide.

5. In combination with a safe, vault or other structure having a doorway or Opening, a door or closure therefor a bar D hinged to the structure and comprising two members a and b hinged or jointed one to the other a strap or slide G secured to the door and 'passing about the bar D, and antifriction-rolls arranged to bear upon the bar and to reduce the friction of the door thereon.

6. In combination with a safe, vault or other structure having a doorway or Opening, a door or closure therefor a bar D hinged to the structure and comprising two members a and b connected by a knuckle-joint or hinge c, having interlocking tenons of a length to preclude buckling of the bar while the door lies against the back of its two parts, and a strap secured to the door, passing about the bar D, and forming a sliding support for the door whereby the latter may be moved to the outer section of the bar to permit the latter to be buckled.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
